We look at the division of 94493002 by 428 
The aim is to understand the frequency of 428 in 94493002.

Step 1:
If we divide 9 by 428, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 428

Advancing to step 2:
The number 428 fits into 94 0 times, leaving a remainder of 94.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 94 leaves us with 94.
Take the next digit (4) from the dividend and append it to 94, then repeat: 944 / 428

On to step 3:
If we divide 944 by 428, we get 2 and a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 856 from 944 to get 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 428

Going ahead to step 4:
If we divide 889 by 428, we get 2 and a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 856 from 889 and we're left with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 428

Advancing to step 5:
When dividing 333 by 428, we get 0 with a remainder of 333.
The next digit of our result is 0. 
Result so far: 220.0
If we take 0 away from 333, we end up with 333.
Take the next digit (0) from the dividend and append it to 333, then repeat: 3330 / 428

Going ahead to step 6:
When dividing 3330 by 428, we get 7 with a remainder of 334.
Record the quotient 7 as the next digit in the result. 
Result so far: 2207.0
The remainder is 334 after subtracting 2996 from 3330.
Grab the next digit (0) from the dividend, add it to 334, then carry on: 3340 / 428

Advancing to step 7:
3340 divided by 428 is 7 with a remainder of 344.
Use 7 as the next digit of our solution. 
Result so far: 22077.0
Subtract 2996 from 3340 to get 344.
Fetch the next digit (2) from the dividend, attach it to 344 and continue: 3442 / 428

Advancing to step 8:
The number 428 fits into 3442 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 220778.0
Subtract 3424 from 3442 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
428 can be fit into 180 0 times, resulting in a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 220778.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
428 can be fit into 1800 4 times, resulting in a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 220778.04
If we subtract 1712 from 1800, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
880 divided by 428 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 220778.042
Deduct 856 from 880 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
240 divided by 428 is 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 220778.042
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
2400 divided by 428 is 5 with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 220778.04205
The remainder is 260 after subtracting 2140 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 14:
When dividing 2600 by 428, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 220778.042056
The remainder is 32 after subtracting 2568 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 15:
428 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 220778.042056
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 16:
The number 428 fits into 3200 7 times, leaving a remainder of 204.
Record the quotient 7 as the next digit in the result. 
Result so far: 220778.04205607
If we take 2996 away from 3200, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Our division results in 220778.04205607 with a remaining 2.04e-07.
